Abstract: PURPOSE: A clock restoring apparatus is provided which easily extracts a clock from a received signal regardless of a modulation method in a communication system such as modem by precisely detecting starting and ending points of a data by inserting a clock burst between data symbols at a transmitting terminal and restoring a clock by the clock burst at a receiving terminal. CONSTITUTION: A clock restoring apparatus which inserts a clock burst pattern into a transmission signal to generate a variety of clocks at a receiving stage and to generate a clock for phase alignment of symbol includes a pre-processor(100) for squaring a received signal to remove phase shift effect and band-pass-filtering it to pass only the frequency component that is twice the symbol frequency to output a square wave signal, a PLL controller(200) for detecting the peak-to-peak signal of the signal band-pass-filtered by the pre-processor to generate a control signal to prevent the operation of a phase locked loop in a data section of the input symbol, and the phase locked loop(300) which normally operates during clock burst section using the output of the PLL controller as a control signal and reduces jitter contained in the output clock of the pre-processor while maintaining a hold state during the data section. The apparatus also includes a clock generator(400) for frequency-dividing the output signal of the phase locked loop and generating a clock signal, and a phase alignment section(500) for extracting a symbol starting point.

Abstract: PURPOSE: A method and apparatus for managing a status is provided to maintain more accurate status management and to restore a detected error automatically by detecting a software error in a digital signal processor(DSP) being used for a call service in a digital mobile communication system. CONSTITUTION: A selector/vocoder processor(SVP) creates a testing packet and transmits the packet to a specific DSP through a bus(S2) in an initial point(COUNT='0')(S1). The DSP codes the transmitted testing packet using a signal processing algorithm being stored in one's SRAM(S3), and performs a decoding again(S4). If the DSP transmits the packet coded and decoded from one's algorithm to the SVP, the SVP compares whether the transmitted packet is identified with the initially created testing packet(S5). In addition, a diagnosis count of the corresponding DSP algorithm is detected. If the transmitted packet is identified with the initially created testing packet and the status is an initial diagnosis process, the normal operation of the DSP algorithm is informed to an operator(S6, S7). If the transmitted packet is not identified with the initially created testing packet and the status is an initial diagnosis process, the SVP performs a reloading the normal algorithm of the corresponding DSP to the corresponding DSP(S8, S9). It is detected whether the corresponding DSP algorithm is normally operated by processing the above (S2¯S5) stages. If the coded and decoded packet transmitted from the DSP is identified with the initially created packet, the SVP decides that an automatically recovery is completed(S10). If the coded and decoded packet transmitted from the DSP is not identified with the initially created packet, hardware of the corresponding DSP is diagnosed(S11). The results of the diagnosis of the DSP algorithm and DSP hardware are outputted and informed to the operator(S12).
